A spring scale meisurs the wecht o an object

In the pheesical sciences, the wecht o an object is the magnitude, W, o the poust that maun be applee'd tae an object for tae support it (i.e. hauden it at rest) in a gravitational field. The wecht o an object equals the magnitude o the gravitational poust actin on the object, less the eftercome o its buoyancy in ony fluid in whilk it micht be doukit in.[1] Naur the surface o the Yird, the acceleration due tae gravity is aboot constant; this means that an object's wecht naurhaund tae the surface o the Yird is rochly proportional tae its mass.

  1. The National Standard of Canada, CAN/CSA-Z234.1-89 Canadian Metric Practice Guide, January 1989:5.7.3 A queer lot o confuision exists in the uise o the term "wecht." In commercial an ilkaday uise, the term "wecht" naurhaund aye means mass. In science an technology "wecht" haes maistlins meant a poust due tae gravity. In scientific an technical work, the term "wecht" shoud be replaced by the term "mass" or "poust," depending on the application. 5.7.4 The uise o the verb "tae wecht" meanin "tae determine the mass o", e.g., "A wecht this object an determined its mass tae be 5 kg," is richt.
